Purpose

An update to software release 10.1.1 for XO-1.5 laptops that is also available for XO-1 laptops.
It is the first release to bring the Fedora 11 base operating environment, Sugar 0.84, and the GNOME desktop to XO-1 laptops.

Installation

XO-1.5

How to install
signed
build
os852
of release
10.1.2

microSD
device. You will need a USB drive of at least 1 GB capacity, but only for the duration of the installation.

Installation progress will be displayed. Green colour will fill
grey
blocks. It will take about
ten
minutes. Once finished,
the laptop will reboot automatically. Remove the USB drive during or after the reboot.
The USB drive can be used on other laptops.

The USB drive can be used on other laptops.

Update

You may wish to update from a previous version of the operating system. This method preserves most user data, Sugar journal and installed Sugar activities, but does not preserve certain operating system customisations such as additional packages.

(Update is distinct from install. If you have followed the install procedures above, then you need not follow this section.)

Compatibility

A few previous versions do not support this method.
Here are the known working update combinations:

We have tested online update from 8.2.1 (ticket #10278). It requires roughly 470MB of free space, 350MB of downloads, and five hours on a high latency connection.

We have tested offline update from 8.2.1. It requires roughly 470MB of free space, 914MB of downloads, and roughly 50 minutes on a laptop with no journal entries.

Following update of the operating system, Software update of activities may require as much as 220MB again depending on what is selected. For release 8.2.1 (build gg-802-1.img) to release 10.1.2 on XO-1, there is not enough free space with the default list of activities, you must delete some first, or remove the previous operating system version before running Software update. See ticket #10278.

(Because of the time and download cost, it may be more appropriate to install afresh, which is roughly 700MB of downloads and no more than about twenty minutes of installation.)

Known Problems

After an operating system update there are a few known problems:

all known wireless access points are forgotten, and you must choose an access point again,

the Browse activity will not start, and must be updated with the Software update icon in My Settings before it will work again,

the "Journal is full" message is likely to appear if not enough space has been made prior to update, and you may need to remove journal entries, activities, or the previous operating system version to bring the system back to normal operation.

Preparation

To prepare for an operating system update:

remove as much saved content as you no longer need,

remove any large activities you no longer need, and;

use Software update to ensure the Terminal activity is the latest available version.

Follow the instructions in one of the subsections below, according to which method and laptop model you are using.

Simple Online Update

establish an internet connection from the laptop (if you plan to do online update),

New features

For new features relative to 8.2.1, please see the New features sections of 10.1.0 and 10.1.1. New features relative to 10.1.1 are:

support for XO-1.5 HS (High School) laptop.

No other new features were added.

Known Problems

Sugar

Record activity video recording may pause

When recording a video of a very complex natural scene, such as moving vegetation, the recording may pause. If this happens, reducing camera movement may allow the laptop to catch up. The pause is visible on playback.

On XO-1.5, switch to Low quality and try again. XO-1 only has Low quality.

On XO-1.5, the class of SD card ordered by the deployment will have some bearing on the video recording performance. Lower class cards such as Class 2 are more likely to experience pauses during recording. Higher class cards such as Class 6 are less likely to experience pauses.

In the previous release 8.2.1, the pause was spread throughout the recording, lowering the effective frame rate. In this release the frame rate is kept as fast as possible until the pause is unavoidable.

Distance activity may be unreliable

When measuring distance greater than about a meter, the activity may begin to report 14m regardless of the distance. This is being tracked by developers in ticket #10122.

Some Language Support Removed

Your language preference may not be available in the Sugar -> My Settings -> Language control panel icon.

Compared to the previous 8.2.1 release for XO-1, this release removes several languages that are not required by the current mass deployments of XO-1.5, in order to conserve disk space on the smallest configuration that can be ordered. The languages Italian, Greek, Thai, Japanese, German, Telugu, and Turkish were among those removed. 150Mb was conserved. This was tracked in ticket #9982.

Under the tree is not automatic when mixing laptop models

In the absence of a wireless access point, a group of mixed XO-1 and XO-1.5 laptops will not automatically begin to collaborate over wireless. A workaround is to create a new wireless network from one of the laptops (frame key, right-click on wireless icon), and then join it from the other laptops. Development is continuing toward a fix, and it is nearly solved, see ticket #9845.

Restoring wireless connection takes too long

It can take between 30 and 35 seconds before wireless access points are detected or the wireless connection is restored after:

GNOME

Repeating file browser window

A new file browser window may appear as the system wakes if a USB or SD card is inserted, ticket #10306.

Fedora

CUPS Documentation

If CUPS is to be installed, the documentation used by the web browser won't be available. To fix this, remove the _excludedocs macro from /etc/rpm/macros.imgcreate before installing CUPS. ticket #10283.

XO-1.5

XO-1.5 External SD cards may not boot

Some types of SD card may not boot when placed in the external slot of an XO-1.5.
This is due to an electrical design error, which is being fixed for XO-1.75.

Solution: upgrade to firmware q3a62 or later, which includes a fix that does not require electrical design change.

XO-1.5 Uncommanded resume may occur in racks

Due to the proximity of the lid sensor activation magnet from an adjacent laptop, the laptop may resume from suspend when placed next to another laptop in a rack. Under a concatenation of other circumstances, such as charging, a running activity, automatic power management disabled, and high room temperature, the laptop may grow quite hot, possibly hot enough to melt the plastic.

Workaround: ensure the laptop is shutdown before placing it in a rack.

XO-1.5 No screen rotation

The screen rotation key (on the bottom left of the display) does not rotate the screen image. It is safe to use, but makes no change. Developers are working on rotation support in the graphics driver. (ticket #9350)

XO-1.5 Record activity preview black on lid close and open

With the Record activity on screen displaying a preview of the camera image, closing the laptop lid for long enough to cause a suspend, and then opening it, results in the preview going black.

If this happens, the preview can be restored by pressing Alt/Tab, or switching between Sugar views using the keyboard keys or the frame icons.

The black preview does not affect the taking of photographs, or recording of video. If a video recording is being made, there will be a segment of time missing in the playback.

in GNOME a new file browser window may appear as the system wakes if a USB or SD card is inserted, ticket #10306.

Bugs fixed

Compared against 8.2.1, the bugs fixed were not thoroughly tracked, but they include many fixes by community volunteers and Sugarlabs. Some of these fixes entered community builds that were released between 8.2.1 and 10.1.2.

Compared against 10.1.1, the bugs fixed are listed below in each of the following builds.

os300

The changes that entered in this build were not tracked. It was intended to be practically identical to os206 released in 10.1.1, but with the addition of XO-1 hardware support.
